Hello Richard, We have used power converters that cover a range of voltage, frequency and current for a few years. The versatility of separate converters providing different power requirements in various labs caused us to move away from a single motor-generator to the converters.
The numbers you suggested below might be handled by a 5000 VA (Volt-Amp) unit. I suggest you forward your requirements to a converter vendor; they will advise you regarding limits in start-up transients. We have a Hewlett Packard unit, a California Instruments unit and a Kikasui unit near the 5kVA size. The price is in the range of $10,000-25,000, depending on whether you buy new, demo, used, or have good negotiating skills. For this size unit, you will probably need more than a single phase power source. Your facilities staff or a qualified electrician can help you here. Good luck, Don Umbdenstock Sensormatic > ---------- > From: Richard Cass[SMTP:[email protected]] > Sent: Friday, June 12, 1998 9:37 AM > To: [email protected] > Subject: generating 50Hz power in the US > > We want to do ongoing testing of an ITE product (here in the US) on > 220 VAC > 50Hz power to simulate the European environment to make sure our > power > supply vendor is doing his job.
